FETTER- -LOCK.

SPECIFICATION forming part of Letters Patent No.390,503, dated Qctcber 2, 1888. Application filed September), 1886. Serial No. 212,459. (No model.)

To aZZ whom it may concern:

Be it known that I, \VILLIAM IVIORAN, of Erie, in the county of Erie and State of Pennsylvania, have invented a new and useful Improvement in Fetter-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to an improvement in fetter-locks, and is especially designed for use in securing the fetters upon live stock for irnpeding their progress or travel.

It consists of a casing composed of two flanged and slotted plates connected and se eurely held together by rivets or screws, in combination with a latch or shackle pivoted between said plates, adapted to be engaged by the foot of a lever, also located within the easing, and a ring or equivalent device on the op posite end of said lever for operating the same to cause it to release the latch or shackle or engage the same; also, in the combination, with said lever, of a suitable spring for acting thereon, for the purpose and substantially as hereinafter set forth.

In the accompanying drawings, Figure l is a front view of my improved lock, showing the rings for the attachment of the ropes or straps; and Fig. 2 is an end elevation of the same.

In the difierent figures of drawings similar letters of reference denote like parts of the device therein illustrated.

A indicates a ring or link of metal. It may be of any preferred form or construction, according to the use for which the same is de signed or required. In the present instance it is made T-shaped for the reception of the strap or collar which passes around the neck of the animal which is to be fettered.

O and 0 represent two metal plates, which compose the casing of the lock. They may be of any preferred form, and upon their in ner adjacent faces they are provided with flanges N N, located correspondingly, so that they will exactly meet when the plates are put together. Thus a casing is formed leaving a space between the plates for the introduction of asuitable locking mechanism, hereinafter described. At the top of these plates (3 0 two perforated lugs or ears, K K, are formed, which receive the ring A, above referred to, for suspending the look from the collar or a suitable strap applied to the animals neck.

The plates 0 G of the casing are secured together or united by means of rivets at suitable points, J, F, and H, as shown in the drawings, or in other suitable manner. Upon one of these rivets, as F, is mounted an elbow or bent lever, B, adapted to be vibrated thereon as a pivot. Said lever lies within or between the plates 0 and G, and at its lower extremity is provided with a foot or lip, B, adapted to engage and uphold the swinging end of a latch or shackle, G. (Shown best in Fig. 1.) Said latch or shackle is pivoted upon the rivet H, which binds the plates 0 O of the casing together, and at or near its pivotal point is provided with a cam extension or shoulder, H, which is adapted to abut against one of the side flanges of the casing and serves to limit the inward throw or progress of the latch or shackle G. The casing-plates C G are cut out immediately above the latch or shackle G to allow for the reception of a ring, I, or looped end of a rope or chain there on, as in ordinary looks. The other end of the lever B extends upward diagonally beyond and outside of the casing-plates O 0 between the ends of the flanges N N, and is provided with a ring, B, or equivalent, to which a small rope may be attached for operating the lever B. The throw of the lever B in one direction is limited by means of the rivet J, hereinabove mentioned, or in any suitable manner, its movement in the opposite direction being controlled by a. spring, D, (shown in dotted lines, Fig. 1,) held in place by means of an end socket-piece, L, and pin E, or in any suitable manner.

As above stated, the lock is suspended from and attached to the collar or strap upon the neck of the animal to be fettered. A rope is then tied to one of the legs of the animal and the end of said rope secured to ring I, which is then placed upon the latch or shackle G, the latter being engaged by the foot B on the 7 lower end of the lever B.

When it is desired to release the animal, or

should the animal get its foot over the rope, a downward jerk upon the small rope attached to the ring 13 will operate the lever B to release the latch or shackle G, and the ring I, to which the rope is secured, will drop from the said latch or shackle and instantly release the animal.

I am aware that in the construction of fetter-locks two casing-plates have been employed united at their edges by a continuous flange or web, and that said web has been provided with openings for the reception of the swinging end of a latch pivoted between the casing-plates of the lock; also, that a block for engaging the foot of the latch has been pivoted between the casing-plates, acted upon by a spring, and that such pivoted block has been adapted to be operated from the out side of the casing by a pin projecting through a slot therein.

Having now described my invention, what I desire to secure by Letters Patent is- In a fetter-lock, the combination, with the inclosing-plates G and 0, provided with the corresponding flanges, N N, and the perforated ears K K, of the ring A, the latch or shackle G, having a cam-shoulder, H, lever B, spring D, and stop J, substantially as and for the purpose described.

In testimony whereof I have hereunto set 0 my hand this 28th day of August, A. D. 1886.
